Enhanced Power-Delivered-to-Load Through Planar Multiple-Harmonic Wireless Power Transmission.

In this brief, a method is presented to enhance the amount of power delivered to load (PDL) by making use of three-harmonic wireless power transmission while it does not occupy larger area than a conventional single-coil system. The proposed system consists of three inductive links each one tuned at a harmonic of the operating frequency. A single power amplifier supplies all of them. Therefore, th...
